## What it is
Middleman is a Ruby-based static site generator that provides templating (ERb, Haml), Sass support, and a live preview server for building fast static websites. It compiles source files into production-ready HTML/CSS/JS deployable to any CDN or static host.

## Use cases
- build a static website with Ruby
- generate static HTML from Haml or ERb templates
- compile Sass stylesheets into CSS for a static site
- preview a static site locally with a dev server
- deploy a fast static frontend to a CDN
- create a marketing site or blog without a backend

## When to choose
- you prefer Ruby tooling for static site generation
- you want Sass, Haml, and flexible templating out of the box
- you need a standalone frontend decoupled from a backend API
- you want a simple build command producing deployable static files

## When to avoid
- you want a JavaScript-based ecosystem like Next.js, Gatsby, or Astro
- you need server-side rendering or dynamic runtime behavior
- you prefer content-first blogging with a large theme ecosystem
- you need a generator with very frequent releases and active development
